why does the JSON response imperfect in Volley Android?

My complete response in Postman is the following but I can't get a complete response as JSON when using Volley android.
My volley code :
I have no problem sending a request but I show my logic that maybe was a problem with my code.
public void makeAssignment(final String token, HashMap<String,String> info_doc , List<Region> result, final OnMakeAssignment onMakeAssignment) {
HashMap<String, String> params = new HashMap<String, String>();
params.put("document_type", info_doc.get("type_doc"));
params.put("title", info_doc.get("title_doc"));
params.put("meter", info_doc.get("meter_doc"));
params.put("price", info_doc.get("price_frosh"));
params.put("mortgage_price", info_doc.get("vagozari_price_rahn")); // رهن
params.put("monthly_rent_price", info_doc.get("vagozari_price_ejareh")); // ejareh
params.put("address", info_doc.get("address"));
params.put("description", info_doc.get("vagozari_description"));
params.put("region[0]", "1");
if (result.isEmpty()){
params.put("region[0]", "all");
}else{
for (int i = 0; i < result.size(); i++) {
params.put("region["+i+"]", String.valueOf(result.get(i).getId()));
}
}
StringRequest stringRequest = new StringRequest(Request.Method.POST, Vars.MAKE_ASSIGNMENT,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
onMakeAssignment.onReceived(response);
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
if (error instanceof NoConnectionError || error instanceof TimeoutError) {
context.startActivity(new Intent(context, NoInternet.class));
onMakeAssignment.onError(error.getMessage());
}
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> params = new HashMap<String, String>();
// params.put(Vars.KEY_AUTH, Vars.AUTH);
params.put(Vars.KEY_AUTH, token);
params.put(Vars.KEY_USERNAME, Vars.USERNAME);
params.put(Vars.KEY_PASSWORD, Vars.PASSWORD);
return params;
}
#Nullable
#Override
protected Map<String, String> getParams() throws AuthFailureError {
HashMap<String, String> params = new HashMap<String, String>();
return params;
}
};
RequestQueue requestQueue = Volley.newRequestQueue(context);
requestQueue.add(stringRequest);
}
The JSON response details are imperfect when I call this method with the Volley library but a response in the Postman is complete. so finally o don't know why this happens because it isn't a problem in requests when using PostMan. so my android Logcat gets back this response when running a method request but unfortunately it isn't the same as the response Postman.

How do you obtain a Auth token using webView in android?

I need to receive the token on my Android aplication..
I created and API on laravel, and i need to receive a token, but i dont know how to do it on android.

It would be difficult to read a token into a WebView and then try to extract it from the WebView. Typically, you just make an HTTP Request to an API method to get the token, then store the token for later use. Here is an example of doing that, which doesn't involve using the WebView:
// You need a URL to an API method that will return the token
if (apiToken.length() == 0) {
getToken("https://mycompany.com/account-services/api/v1/token");
}
private void getToken(String url) {
StringRequest postRequest = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
// Response JSON contains the token
JSONObject obj = new JSONObject(response);
apiToken = obj.getString("access_token");
// Save the token in the shared appPrefs so it can be referenced in other classes
SharedPreferences appPrefs = getSharedPreferences("appPreferences",MODE_PRIVATE);
SharedPreferences.Editor prefsEditor = appPrefs.edit();
prefsEditor.putString("apiToken", apiToken);
prefsEditor.commit();
} catch (JSONException e) {
Log.e("myapp", "JSONException Error: " + e.getLocalizedMessage());
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("myapp", "Response Error: " + error.toString());
}
}) {
#Override
protected Map<String, String> getParams()
{
// Most Token API methods have their own secret user id and password
Map<String, String> params = new HashMap<String, String>();
params.put("grant_type", "password");
params.put("username", "apiusername");
params.put("password", "apipassword");
return params;
}
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
// This API expects the parameters in the form of "grant_type=password&username=apiusername&password=apipassword"
headers.put("Accept", "application/x-www-form-urlencoded; charset=UTF-8");
headers.put("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
return headers;
}
};
// the Request Queue has been declared in the Application object on app startup
MyApplication.getInstance().addToRequestQueue(postRequest);
}

How to make GET request to Yelp api using volley?

I am using Volley to make get request to Yelp Api and keep getting "BasicNetwork.performRequest: Unexpected response code 400 for https://api.yelp.com/v3/businesses/search" error. I made GET request on Postman using the same parameters and headers and it worked just fine. Yelp has released their new API v3 recently,so I did not find any useful similar problem on stackoverflow.
StringRequest stringrequest = new StringRequest(Request.Method.GET,
"https://api.yelp.com/v3/businesses/search",
new Response.Listener<String>(){
#Override
public void onResponse(String response) {
progressDialog.dismiss();
try {
JSONObject jsonObject = new JSONObject(response);
}catch(JSONException e){
e.printStackTrace();
}
}
},
new Response.ErrorListener(){
#Override
public void onErrorResponse(VolleyError error){
progressDialog.hide();
Toast.makeText(getApplicationContext(),error.getMessage(),Toast.LENGTH_LONG).show();
}
}){
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String,String> headers = new HashMap<>();
//headers.put("Content-Type","application/x-www-form-urlencoded");
headers.put("Authorization",[Bearer myToken]);
return headers;
}
#Override
protected Map<String,String> getParams() throws AuthFailureError{
Map<String, String> params = new HashMap<>();
params.put("latitude",latitude);
params.put("longitude",longitude);
params.put("radius","15");
return params;
}
};
RequestHandler.getInstance(this).addToRequestQueue(stringrequest);

What is the best way to save a RequestQueue response?

all. First time posting here.
Anyway, I wrote an Android method that creates a RequestQueue and sends a request to my server via a PHP script to get the server time. The way I have it DOES work, but I'm almost certain it's jury rigged code and there must be a better way to do it.
Bottom Line: I want to save the onResponse response into a String time that I can return (time was a String before being changed to an ArrayList). However, it won't let me use a String from outside onResponse unless it is final. Of course that means I can't change it to response.
I think I'm going about it wrong. Maybe there's a better way to get a response from the PHP script?
The Android method:
public static String getServerTime(Context c){
//Make a final ArrayList that will hold response once received
final ArrayList<String> time = new ArrayList<String>();
//Set up the RequestQueue
RequestQueue requestQueue = Volley.newRequestQueue(c);
String requestUrl = c.getString(R.string.uploadServerUrl)+c.getString(R.string.serverRequestPath);
Response.Listener responseListener = new Response.Listener<String>() { #Override public void onResponse(String response) { time.add(response.toString()); System.out.println("onResponse: "+response.toString());}};
Response.ErrorListener errorListener = new Response.ErrorListener() { #Override public void onErrorResponse(VolleyError error) {System.out.println("onErrorResponse: "+error.toString());}};
StringRequest request = new StringRequest(Request.Method.POST, requestUrl, responseListener, errorListener){
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> parameters = new HashMap<String, String>();
parameters.put("option", "0");
return parameters;
}
};
RetryPolicy retryPolicy = new RetryPolicy(){
#Override public int getCurrentTimeout() {
return 50000;
}
#Override public int getCurrentRetryCount() {
return 50000;
}
#Override public void retry(VolleyError error) throws VolleyError {}
};
request.setRetryPolicy(retryPolicy);
requestQueue.add(request);
return time.remove(0);
}
The PHP script:
<?php
if(isset($_POST["option"])){
$option = $_POST["option"];
switch($option){
case 0:
date_default_timezone_set ("America/Chicago");
$time = time();
echo(date("Y;m;d;H;i;s", $time));
}
}
else{
echo "No option set!";
}
?>

HTTP-Headers not included in request made with Volley

I have the below request but for some reason the headers aren't being "attached" to the request? Please could you maybe assist me with this?
public void get(String servicesUrl, String end_tag_url) {
// Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(Request.Method.GET, url + servicesUrl + end_tag_url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
System.out.println(response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
System.out.println(error);
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("header1", "value");
params.put("header2", "value");
return params;
}
};
// Add the request to the RequestQueue.
queue.add(stringRequest);
}
I get connection to the server but the is an auth failure because the headers aren't being implemented in the connection.
I have tested on a Chrome add-on called Advanced-Rest-Client and added the headers which worked.
I could add 2 of the headers to the URL but the 3rd one cannot be attached to the URL and needs to be a header?

When creating a request, override getHeaders(), like so:
new JsonObjectRequest(url, jsonRequest, listener, errorListener) {
#Override
public Map<String, String> getHeaders() {
Map<String, String> map = new HashMap<String, String>();
map.put("X-REST-API-Key", resources.getString(R.string.parse_api_key));
map.put("X-Application-id",
resources.getString(R.string.application_id));
if (sessionToken != null) {
map.put("X-Session-Token", sessionToken);
}
return map;
}
};
